Fujifilm X-A7 vs X-S10
The Fujifilm X-A7 and the Fujifilm X-S10 are two digital cameras that were announced, respectively, in September 2019 and October 2020. Both the X-A7 and the X-S10 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The X-A7 has a resolution of 24 megapixels, whereas the X-S10 provides 26 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A7 and the Fujifilm X-S10? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Fujifilm X-A7 and the Fujifilm X-S10. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The X-A7 can be obtained in four different colors (silver, graphite, brown, green), while the X-S10 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-S10 is notably larger (32 percent) than the Fujifilm X-A7. Moreover, the X-S10 is substantially heavier (45 percent) than the X-A7. In this context, it is worth noting that neither the X-A7 nor the X-S10 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Fujinon X Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-A7 was launched at a markedly lower price (by 50 percent) than the X-S10, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X-S10 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the X-S10 offers a slightly higher resolution of 26 megapixels, compared with 24 MP of the X-A7. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.92μm for the X-A7). However, it should be noted that the X-S10 is a somewhat more recent model (by 1 year and 1 month) than the X-A7, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the X-S10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The X-S10 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-A7 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Fujifilm X-S10 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 80-51200.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-S10 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A7 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A7, the Fujifilm X-S10, and comparable cameras.
One feature that differentiates the X-S10 and the X-A7 is in-body image stabilization (IBIS). The X-S10 reduces the risk of handshake-induced blur with all attached lenses, while the X-A7 offers no blur reduction with lenses that themselves do not provide optical image stabilization.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Fujifilm X-A7 and the Fujifilm X-S10 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the X-A7 and the X-S10 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm X-A7 and Fujifilm X-S10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X-A7 and the X-S10 are recent models that are part of the current product line-up. The X-A7 replaced the earlier Fujifilm X-A5, while the X-S10 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm website.
So what is the bottom line? Is there a clear favorite between the Fujifilm X-A7 and the Fujifilm X-S10? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Fujifilm X-A7:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Larger screen: Has a bigger rear LCD (3.5" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (2760k vs 1040k dots).
- More compact: Is smaller (119x68mm vs 126x85mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 145g or 31 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (440 versus 325) on a single battery charge.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in September 2019).
Arguments in favor of the Fujifilm X-S10:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
- More modern: Was introduced somewhat (1 year and 1 month) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the X-A7 comes out slightly ahead of the X-S10 (8 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Fujifilm X-A7 and the Fujifilm X-S10 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the X-A7 and the X-S10 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
